STMicroelectronics STEVAL-IFP002V1

Overview

STEVAL-IFP002V1 from STMicroelectronics is an industrial reference design board implementing an 8-channel high-side driver based on the VN808 IC, featuring 16 digital inputs, 2 digital outputs, optocoupler-isolated control/power sections, integrated DC/DC conversion, and IEC 61000-4-4 (4 kV), -4-5 (2 kV), and -4-6 (10 kV) immunity compliance for PLC digital output modules.

For engineers reviewing the STEVAL-IFP002V1 datasheet, STEVAL-IFP002V1 schematic, STEVAL-IFP002V1 application notes, or STEVAL-IFP002V1 alternative evaluation boards, this board provides a validated implementation of VN808-based high-side switching with surge protection, galvanic isolation, and industrial temperature operation (-25°C to +85°C) in a compact surface-mount layout.

Technical Context

The board implements a complete isolated digital output stage for programmable logic controllers, using multi-channel optocouplers (2500 V_RMS isolation) to decouple microcontroller-level logic from 35 V max power supply rails. Transil diodes provide bidirectional clamping against positive/negative transients.

It integrates a DC/DC converter to power the isolated side, supports up to 0.5 A per channel across 16 output channels (configured as 8 high-side drivers via VN808), and meets IEC immunity requirements without external filtering components.

FAQ

What is the primary function of STEVAL-IFP002V1?

STEVAL-IFP002V1 is a reference design board that implements an 8-channel high-side driver solution using the VN808 IC. It provides galvanically isolated digital outputs with integrated surge protection, DC/DC conversion, and IEC-compliant EMC performance for industrial PLC applications.

Does STEVAL-IFP002V1 include power conversion circuitry?

Yes - it integrates an on-board DC/DC converter to generate isolated supply rails for the optocoupler secondary side and VN808 driver logic, eliminating the need for external isolated power sources during evaluation or prototyping.

How does the board achieve IEC 61000-4-5 (2 kV) surge immunity?

By combining uni-directional ST Transil diodes for bidirectional transient clamping on power lines and multi-channel optocouplers (2500 V_RMS) to isolate control signals, the board meets IEC 61000-4-5 Level 3 (2 kV) surge immunity without additional external protection components.

Can STEVAL-IFP002V1 be used directly in production systems?

No - it is a reference design board intended for evaluation, validation, and schematic/layout guidance. While functionally representative, its PCB layout, component selection, and certification are optimized for lab verification, not full industrial qualification or long-term deployment without redesign.
